Gearing question
Recently I have been looking into re-gearing my truck. From what I've heard the best gear ratio to run with 31s would be 4.11. Would it make any sense just to do the rear diff, or would that make 4wd all messed up? Also I am considering running 33s some time in the future, would these gears work ok for them too? Lastly what are a few good company that sell new gear sets?

This sounds like its gonna get expensive real fast
I was hoping to just change the ring and pinions, but thats probally not gonna happen for awhile!

First off, with your truck, you already have 4.10 gears. With 31" tires, you want to go with 4.56's. Second, swapping ring and pinion gears really isn't that difficult once you have all the tools you need. Figure to spend $200 or so just on tools. For a one-time thing, it usually isn't worth it although there are other uses for the tools you'd need. Mostly, setting gears requires a lot of patience, you may have to do it several times in order to get them right and if they are set badly, they will have a very short life. This is what scares away most people from setting their own.

My truck didn't come stock with 31s so im pretty sure that i dont have 4.11 gears. Anyone with 4.56 gears around what rpm are you turning at 60-65mph? I would like to stay at or below 3000 rpms. Thanks for your replies!!!

i would go with a quality gearset, Yukon, US gear, precision, there may be a couple others, but what ever you do don't buy Genuine Gears, trust me on that one

Ive thought about this for a month or so and I was wondering if it would be possible to find a 4runner or truck with stock 31s or and auto and take 4.56 or 4.88 thirds and put them in my truck. Is the possible, I have heard the factory 4.88 thirds are different than 4.56 or 4.10.

Yes, they are different but they will bolt up to your axle housing no problem. The problem with these thirds is that you are stuck with the ratio. The factory 4.88 ratio gears are different (more pnion offset) than regular gears. As such there are no other ratios available that will fit. If you want a different ratio later on, you will need to find different third members and go from there.

Sweet, I dont think I will go any larger 4.88 and I do I could always just use my old 3rd. How hard are these 4.88 thirds to find? Also how hard is the install?

I have 31's, 22RE, 5-speed, and 4.56 gears. 60-65 mph turns the motor about 2500-2750 RPM.
